Glass Tanks ?

I am wondering what type of Resin was used on Fiber Glass gas tanks ? I have a repair that needs to be done to a plastic fuel cell. It is a cell I had in my boat for the '07 Parker 300, it slipped and touched the alt pulley. I am thinking of using Sea Goin Poxy Putty and then sealing it with resin. It will be going back into the steel can after repair. I have heard of the plasic welding deal but I have not had any luck with it. Does anyone have any other Ideas ?

Jim,
I believe that Marine Tex is a similar to the Sea Goin Poxy Putty and therefore would not stick/work.

For me there is too much at stake to risk using a patched fuel container in a boat, even an open boat. Leaks could cause a catastrophic event. But that is me.

There are "epoxy" type products available that are compatible with different plastics. In order to patch the plastic, you need determin the compound (ABS, Polyethylene, etc)and then find an epoxy that is compatible. If your plastic is the same as an automotive product (bumper, etc) you might find what you need at an auto store. I have successfully used some of this epoxy for plastic with fiberglass mat to repair a Thule roof top carrier.
